this project is an intelligent hardware product mainly used to assist the audience rating of hearing impaired people.This product use the advanced speech recognition technology and specialized audio processing technology, the real-time voice into text, and through the intelligent algorithm to generate subtitles, automatic matching output video content after overlay, caption and pictures "a screen" is presented to deaf people, from now on to thoroughly solve the deaf people can't watch without subtitles broadcast video program or number of screen, is only to the quick.Auxiliary subtitle box appearance is shown

Features:

1. Subtitle and video "on the one screen" : With the advanced design concept and the use of advanced voice recognition technology and video and audio processing technology, real-time subtitles can not only be provided, but also the real-time subtitles and the corresponding video can be presented to the hearing impaired through a screen, successfully solving the audience rating needs of the hearing impaired.

2. Intelligent engine recognition, better subtitle accuracy:It integrates the voice recognition engine of domestic first-class manufacturers and combines with the optimization algorithm independently developed by us to ensure more accurate real-time subtitle content.

3. Accurate subtitle push for specific programs: For live news, variety shows, sports and other programs with fixed broadcast time and no subtitles, the auxiliary subtitle box supports receiving and pushing accurate subtitles in the background, which improves the audience understanding of the deaf and the seriousness of the corresponding programs

4. Subtitle can be closed and CC technology pioneer experience : Based on the design concept of "closing captions", superposition captions. When captions are not needed, you can open or close the captions at any time through the "captions button" of the remote control. At the same time, subtitle content can adjust the display position and even font size according to the program and the viewing habits of the deaf
